I am also seeing the "Notice: Undefined index: dataquery.php:query in /var/www/html/lib/functions.php on line 1420" message after installing dataquery. This is running on CactiEZ CD v0.2 Beta with version 1.0 of the plugin architecture. Beyond that, when I perform a data query, the output seems offset as shown in the image below.

Should the dataquery follow the Associated RRAs (daily, weekly, etc) as the graphs do?

It shows the timestamp when the rrd file was created and times from 8:05 am to 9:05am regardless of which graph I click on

In the pre-plugin version the CSV download link would work even if your cacti directory was not under DocumentRoot.

For example, I have cacti installed in /opt/cacti and my DocumentRoot is /var/www/html. The download link links to the full filesystem path of /opt/cacti/plugins/dataquery/csv/filename.csv rather than /cacti/plugins/dataquery/csv/filename.csv
